我有一个来自母活动的

片段

，我想在其中使用

FragmentTabHost

显示两个选项卡。但是我希望选项卡位于片段的底部，而不是顶部，因为这是默认设置

MainFragment.java:

    public class MainFragment extends Fragment {

    private FragmentTabHost tabHost;
    private View rootView;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        //tabHost = new FragmentTabHost(getActivity());
        rootView = inflater.inflate(R.layout.fragment_main, container, false);

        tabHost = (FragmentTabHost) rootView.findViewById(R.id.tabhost);

        tabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);;

        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab 1"), ConnectFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab 2"), ManageFragment.class, null);

        tabHost.setCurrentTab(0);

        return tabHost;

    }
}

我使用的布局非常基本，当我运行这个版本时，一切都正常，但选项卡显示在片段的顶部

fragment\u main.xml:

    public class MainFragment extends Fragment {

    private FragmentTabHost tabHost;
    private View rootView;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){

        //tabHost = new FragmentTabHost(getActivity());
        rootView = inflater.inflate(R.layout.fragment_main, container, false);

        tabHost = (FragmentTabHost) rootView.findViewById(R.id.tabhost);

        tabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent);;

        tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("Tab 1"), ConnectFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("Tab 2"), ManageFragment.class, null);

        tabHost.setCurrentTab(0);

        return tabHost;

    }
}

我可以想象，这辆车出了问题
